This code displays a beautiful GUI as a Window9 example.
However, the generated Sudoku contents do not change.
Please let me know if this code can change the contents of Sudoku.

By the way, I know that the following SuDoku generator can be used with '$lang: "deprecated"' if I just want to generate Sudoku.

I found a SuDoku program written in FreeBASIC at the following site.
http://games.freebasic.net/dumpbyid.php?input=92

This program is able to generate SuDoku problems as well as solve input SuDoku problems very quickly.
Programming a "Sudoku generator and solver" is an interesting task for beginners in programming ;-)

P.S.
What I've found in writing the program is that creating a solvable SuDoku problem is quite difficult.
The problem creation process took many times longer than the problem solving process time.
